Title: Improvements in and relating to electric pulse forming circuit arrangements
IPC: H03K7/08
Filed: 1958-02-28
Abstract: 889,028. Transistor pulse circuits. CONTRAVES A.G. Feb. 28, 1958 [March 1, 1957], No. 6605/58. Class 40(6). A variable pulse delay circuit comprises an electronic switch which is periodically operable to charge a capacitor, a second switch operable to discharge the capacitor at a rate dependent upon a control voltage applied to the second switch, and a third electronic switch which becomes conductive when the capacitor discharges to the value of a voltage applied to the third switch. Upon the occurrence of an input pulse from a multi-vibrator MV a transistor Tl is momentarily rendered conducting to charge a capacitor C until it reaches the voltage of a battery B2 to which the capacitor is connected by a clamping diode Dl. At the end of the input pulse the capacitor discharges linearly through a transistor T2 arranged as a constant current device, the rate of discharge being dependent upon the current supplied to the emitter through a variable resistor P1. The voltage on the condenser is applied to a transistor T3 where it is compared with the voltage from a potentiometer P2 and, when it falls below the potentiometer voltage the transistor T3 becomes conductive and remains so until the next input pulse is applied to transistor Tl. Pulses are accordingly produced in the collector circuit which are amplified in an output transistor T4, the width of the output pulses being linearly dependent upon the value of the voltage obtained from the potentiometer P2 and also on the setting of P1. A silicon diode D2 increases the apparent resistance of transistor T3 when it is not conducting.

The copper compound may be cuprous oxide, copper ocychloride or copper carbonate.  The composition may also include diluents, e.g. china clay, diatomaceous earth or talc, a mineral oil, and an insecticide, e.g. gamma benzene hexachloride.  Examples of suitable dressings are given. Specification 727,241, [Group VI], is referred to.ALSO:Seed dressing for the control of seed-borne fungal and bacterial diseases of cotton comprises finely pulverulent compositions in which the active material is a mixture of paraformaldehyde and a fungicidal copper compound preferably at least 10 per cent. of each being present.  Diluents such as china clay, diatomaceous earth or talc may also be included.  The copper compound is preferably cuprous oxide but other known fungicidal copper salts such as the oxychloride or carbonate may be used. The cuprous oxide may have been previously incorporated with other materials according to its method of preparation, e.g. when precipitated from a solution of a copper salt the oxide is sometimes milled before drying with a suitable dispersing agent such as the salts, e.g. Na, Ca or Mg salts, of the mixture of lignin sulphonic acids derived from sulphite cellulose liquors (convenient preparations of which are sold under the RTM Goulac), the dispersing agent then forming a considerable part of the diluent material and only a small proportion of added diluent is then required.  A water-soluble inorganic salt may be added to the commercial cuprous oxide not previously mixed with dispersing agents as described in Specification 727,241 to improve its fungicidal activity.  A mineral oil in small amounts may be added to cause the composition to adhere to the seeds and to reduce the dust hazard when the dressing is applied and small quantities of an insecticide such as gamma benzene hexachloride may also be included.
